A Combined Ground-based and JWST Atmospheric Retrieval Analysis: Both IGRINS and NIRSpec Agree The Atmosphere of WASP-77A b is Metal-Poor

Peter Smith, Michael Line, Jacob Bean +12

Ground-based, high-resolution and space-based, low-resolution spectroscopy are the two main avenues through which transiting exoplanet atmospheres are studied. Both methods provide…

An Orbital Solution for WASP-12 b: Updated Ephemeris and Evidence for Decay Leveraging Citizen Science Data

Avinash S. Nediyedath, Martin J. Fowler, A. Norris +11

NASA Citizen Scientists have used Exoplanet Transit Interpretation Code (EXOTIC) to reduce 40 sets of time-series images of WASP-12 taken by privately owned telescopes and a 6-inch…

Utilizing a global network of telescopes to update the ephemeris for the highly eccentric planet HD 80606 b and to ensure the efficient scheduling of JWST

Kyle A. Pearson, Chas Beichman, Benjamin J. Fulton +37

The transiting planet HD80606b undergoes a 1000-fold increase in insolation during its 111-day orbit due to it being highly eccentric (e=0.93). The planet's effective temperature i…

Searching for Transit Timing Variations and Fitting a New Ephemeris to Transits of TrES-1 b

Paige Yeung, Quinn Perian, Peyton Robertson +4

Based on the light an exoplanet blocks from its host star as it passes in front of it during a transit, the mid-transit time can be determined. Periodic variations in mid-transit t…

ExoClock project II: A large-scale integrated study with 180 updated exoplanet ephemerides

A. Kokori, A. Tsiaras, B. Edwards +102

The ExoClock project is an inclusive, integrated, and interactive platform that was developed to monitor the ephemerides of the Ariel targets to increase the mission efficiency. Th…

ExoClock Project: An open platform for monitoring the ephemerides of Ariel targets with contributions from the public

Anastasia Kokori, Angelos Tsiaras, Billy Edwards +46

The Ariel mission will observe spectroscopically around 1000 exoplanets to further characterise their atmospheres. For the mission to be as efficient as possible, a good knowledge…

Observing transiting exoplanets with the MicroObservatory: 43 new transit light curves of the hot Jupiter HAT-P-32b

Martin J F Fowler, Frank F. Sienkiewicz, Robert T. Zellem +1

Observations of 43 complete transits of the hot Jupiter exoplanet HAT-P-32b using the MicroObservatory 0.15-m robotic telescope network covering a period of 7 years are presented.…

Utilizing Small Telescopes Operated by Citizen Scientists for Transiting Exoplanet Follow-up

Robert T. Zellem, Kyle A. Pearson, Ethan Blaser +41

Due to the efforts by numerous ground-based surveys and NASA's Kepler and TESS, there will be hundreds, if not thousands, of transiting exoplanets ideal for atmospheric characteriz…

Engaging Citizen Scientists to Keep Transit Times Fresh and Ensure the Efficient Use of Transiting Exoplanet Characterization Missions

Robert T. Zellem, Anya Biferno, David R. Ciardi +16

This white paper advocates for the creation of a community-wide program to maintain precise mid-transit times of exoplanets that would likely be targeted by future platforms. Given…
